Fix file transfer corner cases. Fix zero packet read/write in corner cases with initial read/writes. This affects transfers of 16372 bytes to the device and transfers of 1012 bytes (or packet size - 12) from the device.

Add timeout to lock in MtpServer configure In situations where MtpServer is in a bad state, this will prevent the configure call from blocking indefinitely, which will prevent a few visible problems and allow the state to recover on the next config change.

Retry allocations in case of ENODEV Unlike the read() and write() calls, the ioctl() call does not wait for endpoints to be enabled, which is problematic if ioctls() are the first calls on the usb connection, since they may be called before the endpoints are set up. We'll have to retry if this causes them to fail. Bug: 34822471 Test: Change configs to mtp and ptp Change-Id: I89610b9614c33f0b22535cc68cd0c9b502cb55c9

Make Mtp FFS allocations per session rather than per file Workloads that send a large number of small files could repeatedly allocate and free the buffer, causing fragmentation and eventually running out of allocable memory. Instead have the allocation be once per MTP session, and retry with smaller buffers if it fails initially.

Refactored Mtp driver interface into multiple classes. Added new interface for FunctionFS. This allows most of the driver code to exist in userspace. The driver will automatically use FunctionFS if it is enabled for that device, otherwise it will default to the kernel driver. The intention is to eventually deprecate the kernel driver. Bug: 30976142 Change-Id: I36b8d16ca254fddd995b3ea1bd3d37b0ff4a28f7 Test: New automated tests for MtpFfsHandle, AsyncIO. Manual testing on each device.
